REVOLVING TYPE-BED.

SPECIFICATION forming part of Letters Patent No. 228,680, dated June 8,1880. Application ined April 21, Isn.

To all whom t may concern:

Be it known that I, JOHN W. RICHARDS, of the city of Newark, county ofEssex, State of New Jersey, have invented an Improvement in RevolvingTypeBeds, of which the following is a specification.

The said invention is illustrated in the accompanying drawings, whichrepresent, in-

Figure l, a plan view ofthe type-bed; Fig.

1o 2, a transverse sectional elevation of the same on line y of Fig. l;Fig. 3, a transverse sectional elevation of the same on linez of Fig. 1,showing the lconstruction of one of the ends; Fig. 4L, a longitudinalsection of one end` of the type-bed on line x of Fig. 2, showing thebottom pieces and column-rulesin elevation; Fig. 5, an end view ofthelocking-bar, and Fig. 6 plan view of one of the bottom pieces.

Heretofore the column rules of revolving 2o type-beds have been providedwith feet adapted to enter transverse holdin g-grooves sunk in the faceof the bed, the said grooves being filled with sliding blocks betweenthe points occupied by the rules, so as to provide a comparaz 5 tivelysmooth surface for the columns of type to rest upon; but in suchconstruction it is found, in practice, that the loose type at the sidesofthe columns sometimes slip down between a foot of the column-rule andthe sliding piece in the groove, and thus prevent the type from beingmoved up and drawn in the space between two column-rules in making upthe form, and also prevent the body of types between the column-rulesfrom being locked up lirmly.

The object of the presentiuvention is to avoid the joint at the Sides ofthe columns, where, especially in curved forms, the type are apt to beloose, and thus easily drop down; and the 4o invention consists in aconstruction of parts which brings the joint between the bottom pieceswhich separate the column-rules at a point between the same where thetype are more firmly held.

Rotary type-beds are constructed of a segment of metal, whose base-plate7 is curved transversely on its outer face to an arc a little less thanthe diameter of' the type-cylinder which is to receive it, and providedwith 5o flanged ends ll and sides 20 l2.

Each column-rule 2 is fiXedly held in a bottom piece, 3, which extendsthe whole length of the bed, and is curved to correspond with the faceof the base plate 7. These bottom pieces, 3, are of such width that whentwo are brought together the space between the rules they support isjust equal to the width of a column of type. In order to hold them inplace firmly upon the base-plate 7, they are provided with feet 4,projecting from their under 6o surfaces, which feet, having lateralprojections l l, are adapted to enter rabbeted transverse grooves in thebase-plate 7 of the bed and slide therein. There may be two or more ofthese feet 4, according to the length of the column, and in order thattheir extreme ends may be secure they are provided with tenons 13, whichenter rabbeted grooves 8 in the ends of the type-bed. Two of thesetenons are provided (see Fig. 6) in order that a recess may 7o be formedbetween them to permit the said bottom pieces to pass the jaws 17, whichproject from the end plates, for a purpose to be explained, and enterthe grooves 8.

The bottom piece, 10, which supports the column farthest from, and thebottom piece, 5, nearest to, the locking side of the type-bed, are soconstructed that they may provide on one side of the rule they carry asurface suflicient to support the entire width of a column ot' 8otype-while on the other side they furnish a support for but one half ofthe width of a column of type, the other halt' of said column beingsupported by the next adjacent bottom piece. Between these bottom pieces5 l() the 8 5 columns (to any number) are supported vby bottom pieceswhose surfaces each side of the rules they support are equal toone-half' the width of a column of type.

In making up a form in this improved type- 9o bed, we will suppose thefirst or inside column is set up O11 the bottom piece, l0, between itsrule 2 and the side l2 of the bed. A second column of type may be thenplaced between the rule carried by the bottom piece, l0, and thatcarried by the bottom piece, 3, and so O11 until the type-bed is lled,except with its last or outside column of type, the intermediate columnsof type, or those between the inside and outside columns, beingsupported on bot- Ioo tom plates whose joining-seam is midway, or nearlyso, between the column-rules. rlhese bottom plates are enteredvertically past the jaws 17, andare slid laterally in the rabbetedgrooves S, their feet 4t passing into the transverse groove 6 in thebottom plate, 7, of the type-bed. To provide for their thus beingentered, the end plates, l11, are cut away or recessed, as at 15, andthe overhanging edges ot' the transverse orooves 6 are cut awav seedotted lines, Fig. 1) for a distance at the entrance side which is equalto the length ofthe l'eet el. of the said bottom plates.

The ledge necessary to support one side of the outside column of typeresting on the bottom plate, 5, is at'torded by one side ot'- th'elocking-bar 9, which is ot' such a thickness as to extend upward nearlytype-height. rllhis locking-bar is provided with tenons 14, the bottomsol" which are extended by projections 1S (see Fig. 5) ot' a thicknessadapted to iit into the groove 8 and under thejaw 17. The length of theprojections 1S is such as will )erniit them to enter the recesses 15.

The various parts having been placedin position with the columns ot'type supported by them, lateral pressure is applied to the locking-bar9, which forces the bottom pieces, 5 3 1U, tightly together and towardthe side plate, 12, thus compressing the columns of types between therules and side supports and holding them rmly in place.

In this invention the column-rules areneither provided with 'li'eetentering' the transverse grooves in the bottom ot' the bed nor withtenons entering the grooves in the ends of the bed, which constructionhas heretofore been given them, so that they would perform the double4function oi' aiding-in holding their place in the bed and of clampingthe types in place. ln

the present construction they are subjected to no strain save that ofholding the types in place. l

The means herein illustrated for applying the pressure to the side bar,9, necessary to lock up the 'form is sct-screws 19, tapped through theside plate, 20; but, as will readily be understood, the common means foreffecting the locking up ot forms may be used. Among these means may beenumerated quoins and wedged faced side-sticks, one of which is drivenlongitudinally upon the other by a screw or rack and pinion.

Each separate column may be adjusted longitudinally by pressure appliedto its end either by screws or wedges.

It is not essential that the line of division between the bottom platesshall be centrally between the column-rules, so long as it is far enoughfrom the edge of the column of type as to support the types where, beinga compact mass, they are supported on all sides, and therefore lack thetendency to slip one away from the other, as is the case with the typesat the edge of a column of types.

The type-bed thus constructed may be xed upon the type-cylinder in anyapproved manner.

WV hat therefore is claimed is 1. A type-bed the bottom plates whereofsupport fxedlythe column-rules at a distance from their edges,substantially as described.

2. rlhe combination of the bottom plates, having column-rules attachedto their faces and provided with Han ged feet, with the baseplate havingrabbeted grooves 6, substantially as described.

3. The combination of the bottom'plates, having column-rules attached totheir faces and provided with hanged feet 4 and tenons 13, with thebase-plate having rabbeted transverse grooves (3 and rabbeted grooves 8,substantially as described.

In testimony whereof I have signed my name to this specification in thepresence ot' two subscribing witnesses.

JOHN W. RlCHARDS.
